The study was conducted to preliminary evaluate knowledge, attitudes, and practices (KAP) of communities regarding solid waste management in Vinh Trung commune, Vi Thuy district, Hau Giang province using a questionnaire survey. The results of this study show that the amount of solid waste was generated ranged from 0.5-1.2 kg per household per day with an average of 0.24 kg per capita per day. The household solid waste contained organic waste (85.43%), reusable waste (13.94%), and other components (0.64%). Most people (> 90%) have knowledge about the effects of solid waste disposal on environmental quality, and the benefits of source separation via television and radio. Local authorities have not done well in improving communities’ awareness. The participants have very good attitudes in being willing to sort, pay the garbage collection fee, help each other to increase public awareness. However, the investigated results of the practice survey were contrary to the results with knowledge and attitudes. Therefore, it is very important to provide the public with solid waste management infrastructure and simultaneously support the local authorities in raising propaganda about waste separation and recycling activities.
